Definitions

  • the present invention relates to new 3-piperidineamines or 3-azephineamines substituted, their preparation and their therapeutic applications.
  • the 1-alkyl-2-alkoxymethyl-N-phenyl N-benzyl or N-benzoyl-3-piperidineamines or 3-azepineamines substituted according to the invention correspond to the following general formula: in which R and R ⁇ each represent an alkyl or cycloalkyl radical having 1 to 7 carbon atoms; X represents - O - or H2; Y and Z represent hydrogen or one or more radicals chosen from halo, hydroxy, linear or branched alkyl having 1 to 6 carbon atoms, alkoxy having 1 to 6 carbon atoms, trifluromethyl or methylenedioxy, n being able to take the values 2 or 3.
  • the invention also relates to the salts of said compounds with pharmaceutically acceptable organic or inorganic acids, such as hydrochloric, fumaric, maleic, citric or succinic acids, these acids being mentioned only by way of illustration but without constituting a limitation.
  • pharmaceutically acceptable organic or inorganic acids such as hydrochloric, fumaric, maleic, citric or succinic acids, these acids being mentioned only by way of illustration but without constituting a limitation.
  • the substituent R represents one of the isobutyl, methyl or cyclohexyl radicals; R ⁇ represents the methyl or n-propyl radical.
  • the compounds of the invention can be prepared from 2- ( ⁇ -hydroxy- ⁇ -alkoxy) ethyl pyrrolidine or-piperidine, according to the reaction scheme below:
  • halogenation of a 2- ( ⁇ -hydroxy- ⁇ -alkoxy) ethyl pyrrolidine or piperidine is carried out using a usual halogenating agent such as SOCl2, PBr3 in a solvent such as chloroform , at a temperature between room temperature and the solvent reflux temperature.
  • the halogenated derivative formed may have structure I or structure II, or else be a mixture of the two types of structure.
  • the product obtained in the previous step is condensed with a substituted benzylaniline or benzoylaniline preferably in the presence of a strong base such as sodium or lithium amide.
  • this second step can be carried out by phase transfer in the presence of a strong base such as a 50-70% sodium hydroxide solution and a catalyst such as benzyl triethylammonium chloride , adding, if the viscosity of the medium requires it, a solvent such as toluene or methylene chloride.
  • a strong base such as a 50-70% sodium hydroxide solution
  • a catalyst such as benzyl triethylammonium chloride
  • This reduction can be carried out by means of the usual agents such as lithium aluminum hydride, diborane, in a solvent such as ether or tetrahydrofuran.
  • the compounds of the invention are extracted from the reaction mixture by the usual methods (for example extraction with ether or with methylene chloride) and then purified by preparative liquid chromatography. They can also be extracts by formation and crystallization of a pharmaceutically acceptable salt.
  • a first step 100 g (0.5 M) of 1-methyl-2- ( ⁇ -hydroxy- ⁇ -isobutoxy) ethyl pyrrolidine were introduced into a reactor containing 1 l of anhydrous chloroform, then heated to 50 ° C. and introduced dropwise a solution of 82 ml of thionyl chloride in 80 ml of anhydrous chloroform, and maintained for 4 hours while heating at reflux of solvent.
  • the mixture was then heated at 85 ° C for 3 hours, then allowed to cool, decanted and washed the aqueous phase with methylene chloride.
  • the organic phases were combined, washed with water, dried over sodium sulfate, then the solvent was evaporated.
  • the compounds of the invention have been found to have interesting antianginal properties, with bradycardizing, antitachycardizing and coronarodilator effects.
  • Anticalcic activity was sought according to the technique of Van Rossum (Arch. Int. Pharmacodyn. Ther. 143 , 299-330, 1963).
  • the electrically stimulated rabbit papillary muscle was used (frequency 1.5 Hz; 5 ms pulse of 15 v).
  • the spiral rabbit aorta was used and kept in a solution devoid of Ca++ and enriched in K+ (6 mg / l of KCl). The measurements have been performed 15 minutes after adding the compounds to the solution.
  • the classic parameters of molecular pharmacology are reported in Table II.
  • the compounds are administered I.V. at a dose of 5 mg.kg ⁇ 1.
  • all of these compounds can be, to different degrees, antianginal and / or anti-ischemic due to their bradycardising, coronarodilating and anti-tachycardizing activities.
  • the one with the most interest is the compound No. 4 with a vascular tropism and only significant hemodynamic activity.
  • the toxicity was evaluated orally in mice and no death was observed up to the dose of 500 mg.kg ⁇ 1.
  • This set of pharmacological properties therefore allows the application of the compounds of the invention in human therapy as a medicament for the treatment of cardiovascular disorders, such as angina, ischemia or hypertension.
  • the compounds of the invention can be administered orally or parenterally at daily doses of between 0.5 mg and 10 mg per kg of body weight according to the method of administration.
  • a daily dose of between 50 and 500 mg is preferably used.
  • the compounds of the invention can be put in unit form such as pills, tablets, coated tablets, or else packaged in capsules.
  • the compounds of the invention can also be used in injectable preparation, or in oral preparation in the form of solutions, suspensions or emulsions.
